The experiment showed that the neurons in the face map had invaded the area of the hand-and-arm map, which had been inactive for twelve years. The only thing separating you from Lance and me is your bloody skin, right? Ramachandran believed it was not coincidental that the fusiform gyrus, where number shapes are processed in the brain, lies next to the area where colors are processed.

According to this notion, Jamieson was missing the neurons in the map that corresponded to his right leg from the mid-thigh down. This remark prompted Laura Case, a first-year graduate student who has focussed on autism, to speak. To that end, he had scheduled a meeting with Dr.
